Familial hemiplegic migraine (FHM) is a rare autosomal dominantly inherited subtype of migraine with aura. The clinical characteristics of FHM have been described previously in selected materials or case studies, but population-based studies are important in order to analyse the full spectrum of the disorder. The aim of the present study was to perform a systematic search for familial cases of ...

This is a qualitative and chronological analysis of ictal and postictal symptoms, frequency of seizures, family history, response to treatment, and prognosis in nine patients with idiopathic occipital epilepsy and visual seizures. Ictal elementary visual hallucinations are stereotyped for each patient, usually lasting for seconds. They consist of mainly multiple, bright coloured, small circular...

BACKGROUND AND PURPOSE Serotonin is one of the most potent constrictors of cerebral blood vessels and is implicated in several pathological conditions, including migraine and cerebral ischemia. Recent evidence has suggested that tyrosine kinase is involved in vasocontractile responses. The objective of this study was to test the hypothesis that activation of tyrosine kinase contributes to serot...

Migraine headache is widely believed to be associated with cerebral or meningeal vasodilatation. Human evidence for this hypothesis is lacking. 3 Tesla magnetic resonance angiography (3T MRA) allows for repetitive, non-invasive, sensitive assessment of intracranial vasodilatation and blood flow. Nitroglycerine (NTG) can faithfully induce migraine attacks facilitating pathophysiological studies ...

Recurrent episodes of abdominal pain are common in childhood. Among the diagnostic possibilities are migraine and abdominal epilepsy (AE). AE is an infrequent syndrome with paroxystic episodes of abdominal pain, awareness disturbance, EEG abnormalities and positive results with the introduction of antiepileptic drugs. We present one 6 year-old girl who had short episodes of abdominal pain since...

High intensity sound was used to produce localized hair cell damage within the basilar papilla of chicks at three different ages: embryonic day 20, post-hatch day 10 and post-hatch day 30. At each age separate groups of animals were exposed to broadband white noise or pure tones at 500, 1500 or 3000 Hz for 12 h at 125 dB SPL. Chicks were killed 10 days later. Their basilar papillae were then fi...

A 35-year-old man with Marfan syndrome presented to the emergency room with a severe occipital headache of several hours duration . The headache differed from his usual migraine headaches both in quality and in unresponsiveness to Cafergot. The patient's medical history included repair of an ascending aortic aneurysm and replacement of a bicuspid aortic valve 2112 years previously. The patient ...
